Advent: (Latin adventus, “coming”)
In Western Christianity it spans four Sundays starting with the closest Sunday to November 30th concluding on Christmas Eve.
It begins around November 15th in Eastern Orthodox Churches.
It is a period of repentance, fasting and the preparing the believer for the Second Coming of Christ, aka the Day of Judgment.
Today, fasting is not followed however it still is in some of the Eastern Orthodox Churches.
The Royal colors of blue and purple are integrated into the bulk of Advent Services.
In a lot of countries it is apparent by a variety of popular acknowledgments. On each of the four Sundays before Christmas, Advent Candles are lit.
